secTcpSynCkiOpState

Module: SECURITY-MANAGEMENT-MIB

OID (symbolic): SECURITY-MANAGEMENT-MIB::secTcpSynCkiOpState

OID (numeric): 1.3.6.1.4.1.6889.2.1.14.1.2.1

Node type: OBJECT-TYPE

Type: OnOffType

Access: read-only

Description: Monitors the operational state of the TCP SYN cookies defense mechanism.

The operational state of the SYN cookies can change only after a reset, if the configuration state was changed and the running configuration was saved to the startup configuration before the reset.

Use secTcpSynCkiCfgState to monitor and change the SYN cookies configuration state.

When the SYN cookies feature is turned on, it helps protect the local host from SYN attacks (a type of DoS attack).

What is secTcpSynCkiOpState?

Reports whether TCP SYN cookies (a defense against SYN-flood DoS attacks) are actually active right now; because this operational state only updates after a reset following a saved configuration change, it can lag behind secTcpSynCkiCfgState until the device is rebooted.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.6889.2.1.14.1.2.1
snmpwalk -v2c -c public <target> SECURITY-MANAGEMENT-MIB::secTcpSynCkiOpState

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.6889.2.1.14.1.2.1.1
snmpget -v2c -c public <target> SECURITY-MANAGEMENT-MIB::secTcpSynCkiOpState.1
